We introduce the notion of “δ-complete decision procedures” for solving SMT problems over the real numbers, with the aim of handling a wide range of nonlinear functions including transcendental functions and solutions of Lipschitz-continuous ODEs. Given an SMT problemϕ and a positive rational number δ, a δ-complete decision procedure determines either that ϕ is unsatisfiable, or that the “δ-weakening” of ϕ is satisfiable. Here, the δ-weakening of ϕ is a variant of ϕ that allows δ-bounded numerical perturbations on ϕ. We (...) establish the existence and complexity of δ-complete decision procedures for bounded SMT over reals with functions mentioned above. We propose to use δ-completeness as an ideal requirement for numerically-driven decision procedures. As a concrete example, we formally analyze the DPLL〈ICP〉 framework, which integrates Interval Constraint Propagation in DPLL, and establish necessary and sufficient conditions for its δ-completeness. We discuss practical applications of δ-complete decision procedures for correctness-critical applications including formal verification and theorem proving. (shrink)

Given any collection F of computable functions over the reals, we show that there exists an algorithm that, given any sentence A containing only bounded quantifiers and functions in F, and any positive rational number delta, decides either “A is true”, or “a delta-strengthening of A is false”. Moreover, if F can be computed in complexity class C, then under mild assumptions, this “delta-decision problem” for bounded Sigma k-sentences resides in Sigma k. The results stand in sharp contrast to the (...) well-known undecidability of the general first-order theories with these functions, and serve as a theoretical basis for the use of numerical methods in decision procedures for formulas over the reals.

Epistemic injustice has rapidly become a powerful tool for analysis of otherwise hidden social harms. Yet empirical research into how resistance to knowing and understanding can be generated and replicated in social programmes is limited. We have identified a range of subtle and not-so-subtle inflections of epistemic injustice as they play out in an intervention for people with chronic depression in receipt of disability benefits. This article describes the different ‘species’ of epistemic injustice observed and reveals how these are unintentionally (...) produced at frontline, management, commissioning and policy levels. Most notably, there remains a privileging of clinical knowledge over other forms of knowledge, producing a ‘pathocentric epistemic complex’. This, combined with the failure of different agencies with competing ideologies to adequately understand each other, and a vicious policy context, added to the injustices already faced by people with mental health issues, generating multiple harms. This has important implications for a range of integrated care and welfare interventions – not least by drawing attention to their unintended potential for replicating epistemic injustice as an institutionalised complex. Careful evaluation and design of such programmes, applying the philosophical and epistemic resources illustrated here, can help mitigate this outcome. Further, by raising awareness of epistemic injustice among programme participants, we can generate epistemic structures that secure programme integrity locally, and promote better policy. (shrink)

BackgroundSome people with progressive neurological diseases find they need additional support with eating and drinking at mealtimes, and may require artificial nutrition and hydration. Decisions concerning artificial nutrition and hydration at the end of life are ethically complex, particularly if the individual lacks decision-making capacity. Decisions may concern issues of life and death: weighing the potential for increasing morbidity and prolonging suffering, with potentially shortening life. When individuals lack decision-making capacity, the standard processes of obtaining informed consent for medical interventions (...) are disrupted. Increasingly multi-professional groups are being utilised to make difficult ethical decisions within healthcare. This paper reports upon a service evaluation which examined decision-making within a UK hospital Feeding Issues Multi-Professional Team.MethodsA three month observation of a hospital-based multi-professional team concerning feeding issues, and a one year examination of their records. The key research questions are: a) How are decisions made concerning artificial nutrition for individuals at risk of lacking decision-making capacity? b) What are the key decision-making factors that are balanced? c) Who is involved in the decision-making process?ResultsDecision-making was not a singular decision, but rather involved many different steps. Discussions involving relatives and other clinicians, often took place outside of meetings. Topics of discussion varied but the outcome relied upon balancing the information along four interdependent axes: Risks, burdens and benefits; Treatment goals; Normative ethical values; Interested parties.ConclusionsDecision-making was a dynamic ongoing process with many people involved. The multiple points of decision-making, and the number of people involved with the decision-making process, mean the question of ‘who decides’ cannot be fully answered. There is a potential for anonymity of multiple decision-makers to arise. Decisions in real world clinical practice may not fit precisely into a model of decision-making. The findings from this service evaluation illustrate that within multi-professional team decision-making; decisions may contain elements of both substituted and supported decision-making, and may be better represented as existing upon a continuum.

As Newton realized, his absolute space was a ‘conspiracy of nature’ in the sense that his laws dictated that nobody could discover who, among all possible observers (in various states of motion relative to one another), was at rest in absolute space. So absolute space was an unverifiable element of his theory.

This book offers both the theoretical background behind the minority effect, teachers' personal experiences as they experienced being a minority, and their analyses and insights for teaching diverse learners. This book uses real-life experiences of diverse people to illustrate that, if not understood and addressed, situational minorities at school or work are unlikely to perform at their highest potentials.

This article posits that Andy Clark’s model of distributed cognition manifests socially through the agonism of human activity, and that rhetorical theory offers an understanding of human conflicts as productive and necessary elements of collective response to situation rather than as problems to be solved or noise to be eliminated. To support this assertion, the paper aligns Clark’s argument that cognition responds to situated environmental conditions with the classical concept of kairos, it associates Clark’s assertion that language structures behavior with (...) the long-held rhetorical stance that language is constitutive, and it examines the online encyclopedia Wikipedia as an enactment of what Clark and rhetorical theorists claim about productive agonism and the litigious nature of identity and cognition.

Consider the sentence “Lois knows that Superman flies, but she doesn’t know that Clark flies”. In this paper we defend a Millian contextualist semantics for propositional attitude ascriptions, according to which ordinary uses of this sentence are true but involve a mid-sentence shift in context. Absent any constraints on the relevant parameters of context sensitivity, such a semantics would be untenable: it would undermine the good standing of systematic theorizing about the propositional attitudes, trivializing many of the central questions of (...) epistemology, the philosophy of mind, and the philosophy of action. In response to this problem, we prove a series of tenability results. We show that, given certain constraints on the parameters of context sensitivity, there is a broad class of principles of propositional attitude psychology whose good standing follows from corresponding claims about people’s mental representations. But these constraints also have some surprising consequences: they are jointly incompatible with coarse-grained theories of propositions, and they are in tension with a natural picture of how speakers and hearers coordinate on the interpretation of attitude ascriptions. In light of these consequences we explore different ways in which the contextualist picture might be developed, and argue that our preferred way compares favorably with Fregeanism and neo-Russellianism.

This paper challenges both the traditional view of L. Stephen and E. Albee that Bentham's attitude towards religion was irrelevant to his moral and political thought, and the revisionist critique of J.C.D. Clark and J.E. Crimmins that his religious radicalism was the prerequisite for his political radicalism. It also challenges the two further claims advanced by Crimmins: first, that Bentham was an atheist; and second, that he wished to eliminate religion from the mind. In contrast it is argued that Bentham's (...) theory of logic and language lay at the foundation of his thought. His religious radicalism was therefore not the prerequisite for his political radicalism, but rather one aspect of it. Moreover, Bentham never committed himself to atheism, and advocated religious freedom rather than any form of enforced belief or non-belief. It is suggested that unless historians recognize the centrality and originality of Bentham's theory of logic and language, they will fail to explain adequately the emergence of his distinctively utilitarian political radicalism.

MacIntyre, Clark, and Heidegger would all agree that the current problem with moral theory is its lack of a satisfactory conception of human telos. This lack leads us to resort to such fictions as rights, interests, and utility, which are “disguises for the will to power.” Ibid., p. 240. These thinkers would also agree that modern nation-states are cut off from the roots of the Western tradition. Modern political economy, with “its individualism, its acquisitiveness and its elevation of the values (...) of the market to a central social place”Ibid., p. 237. is leading us into “the coming age of barbarism and darkness.”Ibid., p. 244. MacIntyre's grim depiction of the future, which Heidegger calls “the time of the darkening of the earth” and “the flight of the gods”,Heidegger, “What Are Poets For?” in Poetry, Language, Thought. can only be met by re-appropriating our own tradition. Although Aristotle has much to tell us, I believe Heidegger is right to turn to Heraclitus for a non-anthropocentric conception of humanity's place in Nature. Other writers, however, such as Arne Naess, George Sessions, and Stuart Hampshire, argue that the writings of Spinoza may offer the most helpful vision of humanity needed to guide our efforts to find a more appropriate basis for our behavior toward each other and toward the non-human world as well.George Sessions, “Spinoza and Jeffets on Man in Nature,” Inquiry 20 (1977):481–528. Sessions' essay was criticized by Genevieve Lloyd in “Spinoza's Environmental Ethics,” Inquiry 23 (1980):293–311. In reply, Arne Naess wrote “Environmental Ethics and Spinoza's Ethics: Comments on Genevieve Lloyd's Article,” Inquiry 23 (1980):313~ 325. Cf. also Stuart Hampshire, Two Theories of Morality (Oxford: Oxford University Press, 1977). Yet Aristotle, Qark, Heidegger, Heraclitus, Maclntyre, and Spinoza all agree that in order to behave fittingly, we must understand what it means to be human. At this time, I would like to acknowledge the importance of the following objection to what I have been arguing here: While it may be true that the concept of human rights is a fiction, it is nevertheless a very useful fiction for changing how human beings relate to each other. Tom Regan has frequently pointed out that even if the concept of rights proves to be ficticious, it can be helpful in protecting non-human beings from abuse by humans. Cf. his essay “Exploring the Idea of Animal Rights,” Animals' Rights - A Symposium (Sussex and London: Centaur Press Ltd., 1979); Regan, “Animal Rights, Human Wrongs,” Environmental Ethics 2 (1980):99–120. The doctrine of the rights of man justified the American and French revolutions, which brought forth new and important human freedoms. Today, most of humanity still lacks the protection afforded by constitutionally guaranteed human rights. Moreover, even in constitutional democracies there are frequent abuses of and attempts to curtail human rights. Until far more people become committed to protecting human rights, it is unlikely that there will be a big movement to extend rights to non-human beings, much less to overcome the anthropocentrism inherent in the concept of rights. What the Buddhist tradition calls “skillful means” is appropriate in our current situation.My thanks to Professor David Levin of Northwestern University for having reminded me of the importance of approaching the question of human rights in a “skillful” way. We must approach people in a way sensitive to their current self-understanding. Before we can pass on to the stage of planetary unity made possible by non-anthropocentric thinking, we need to find ways that promote mutual respect among human beings.On the topic of the relation between spiritual-psychological growth and the shift in human morality, cf. M.W. Fox, “Animal Rights and Nature Liberation,” in Animals' Rights - A Symposium. Out of such respect there can also arise respect for the non-human as well. While largely in agreement with this point of view, I would like to note that our means must be very skillful, indeed, if we are to transform our relationships to each other and to the natural world before irreparable damage is done to the earth, through nuclear war or environmental destruction. The time grows short for the transformation needed to bring us from the stage of anthropocentrism to a deeper awareness of our internal relationship to the whole world. Some people, such as Peter Russell, argue that we are witnessing the evolution of a non-anthropocentric mode of planetary consciousness that will be supported by the revolution in communications and computers. Peter Russel, The Global Brain: Speculations on the Evolutionary Leap tp Planetary Consciousness (New York: J.P. Tarcher, 1983). Other people, such as Jeremy Rifkin, maintain that the coming computer age promises ever greater intrusions into natural processes, such as the drive for control of genetic structures.Jeremy Rifkin, Algeny (New York: Viking, 1983). In my view, while it is important to extend the idea of human rights wherever possible, it is also crucial that we consider seriously the possibility that the idea of human rights is merely a transitional way of conceiving of morality. As we learn more about the interrelationship of human life with all other aspects of the earth's life, our self-understanding will no longer be in harmony with the human-centered morality we know today. We will either learn to respect all beings and act toward them in appropriate ways, or else we will continue down the road we are now headed - a road which seems to have a very disturbing destination. Learning to dwell appropriately on earth is the most pressing moral issue of the day. (shrink)

W. Norris Clarke's metaphysics of the universe as a journey rests on six major positions: the unrestricted dynamism of the mind, the primacy of the act of existence, the participation structure of reality, and the person, considered as both the starting point of philosophy and the source of the categories needed for a flexible contemporary metaphysics. Reflecting on his conscious life and the universe around him, the finite person mounts by a two-fold path to its Infinite source, who, though (...) immutable in His natural being, is mutable in the intentional being of His personal knowledge and love. The personal God is the efficient cause from whom the universe comes and the final cause to whom it returns.Less optimistic than Norris Clarke, John Caputo wonders about his metaphysics of the person. In a hermeneutical interpretation of the human face, the person through whom Being "sounds" discloses an ambiguous Being that both reveals and conceals itself. Far from grounding a casual ascent to God, hermeneutical phenomenology allows us no more than the right to interpret the world and its transcendent source through our own free decision.Although impressed by Norris Clarke's attempt to introduce mutability into God, Lewis Ford still finds Clarke's Thomistic God unacceptable. As a Whiteheadian, he proposes in place of Thomas' God, whose perfection consists in static unity, a God whose perfection consists in a never-ending process of unification. John Smith argues against the traditional dichotomy made between the ontological and cosmological arguments. Rather than opposed methods of proving God's existence, they should be taken as complementary journeys to the divine presence which discloses itself, although diversely, in the soul and in the world. There are parallels between Smith's historical study of two arguments and Clarke's two-fold path to God. Yet Smith is critical of Thomas' cosmological journey to God and does not share Clarke's confidence in its validity. Significant studies in their own right, the three essays as a group challenge Clarke's whole metaphysics of the universe as a journey. Meeting the challenge, Clarke clarifies and refines his own thought.An account of Clarke's philosophy by Gerald A. McCool, S.J. preceds this unified and stimulating philosophical discussion.

Descartes is possibly the most famous of all writers on the mind, but his theory of mind has been almost universally misunderstood, because his philosophy has not been seen in the context of his scientific work.

For Clarke, the key is to interpret his philosophical efforts as an attempt to reconcile his scientific pursuits with the theologically orthodox (...) views of his time. (shrink)

This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects on the (...) compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

I argue that knowledge is a natural kind found in the modules of a massively modular mind. As such, it is not a conceptual kind. The result is that knowledge must be studied empirically and not by appeal to a priori analysis.

In this review, I survey theoretical accounts of exploitation in business, chiefly through the example of low wage or sweatshop labor. This labor is associated with wages that fall below a living wage standard and include long working hours. Labor of this kind is often described as self-evidently exploitative and immoral (Van Natta 1995). But for those who defend sweatshop labor as the first rung on a ladder toward greater economic development, the charge that sweatshop labor is self-evidently exploitative fails (...) adequately to explain the nature of the alleged wrongdoing. While all sides might agree that poor working conditions are unfortunate and undesirable, defenders of sweatshop labor argue that they provide the best available employment alternative for some workers and the best chance at economic development for many low and middle income countries (LMICs). Some defenders of sweatshop labor even embrace the label of exploitation. <br><br>Unless there is a clear, widely understood account by which exploitation is a moral wrong, then charging a practice as exploitative will do little to advance debates over whether and why a practice is morally problematic. A considerable body of work has been developed applying a growing literature on exploitation to sweatshop labor. While many forms of moral wrong are associated with sweatshop labor, I will focus specifically on the worry that low wages allow relatively wealthy employers wrongfully to take advantage of or gain from relatively poor workers, especially in LMICs. In particular, I will focus on instances of alleged exploitation in employment relationships that are voluntary and mutually beneficial. I have two reasons for doing so. First, by restricting this review to voluntary and mutually beneficial instances of exploitation, I can isolate the moral wrong of exploitation from other moral wrongs, especially the wrongs of coercion and outright harms to workers. Second, the focus on mutually beneficial and voluntary relationships will allow for arguments that sweatshop labor is not only not exploitative, but is a morally praiseworthy means of helping to encourage economic growth in poor areas of the world and to provide jobs that pay better and are more stable than any existing alternatives.<br><br>In this review, I aim to accomplish three goals. First, I will provide an overview of the many different uses of the charge of exploitation in business practice through an examination of the uses of the term in the literature on sweatshop labor. While it is often not clear what kind of moral wrong is assumed to take place when the charge of exploitation is used, I will demonstrate that many distinct types of exploitation, connected to distinct moral wrongs, are used in the literature on sweatshop labor and elsewhere in business ethics. Specifically, I will identify two broad categories of exploitation—exploitation as unfairness and exploitation as the mere use of others—with subgroups under each main category of exploitation. Second, I will discuss which of these senses of exploitation are defensible as identifying clear moral wrongs that take place in the context of business and, specifically, sweatshop labor. As I will argue, not all uses of the charge of exploitation are capable of persuasively identifying clear moral wrongs. Moreover, there is not a single, clear type of exploitation that takes place in business but, rather, several distinct forms. Third, I will apply the lessons learned from my exploration of exploitation in sweatshop labor to other specific areas of business. As I will argue, there are multiple viable models of exploitation in the sweatshop literature that can illuminate exploitative practices of relatively well compensated employees, customers, suppliers, and entire communities. <br><br>While discussions of theories of exploitation tend to argue for a single, correct account of this moral wrong, my review of the literature on exploitation in sweatshop labor supports the conclusion that there are multiple defensible accounts of the moral wrong of exploitation. For this reason, those who would charge that a relationship is exploitative should specify the form of exploitation that they believe is taking place. (shrink)

Scanlon’s Being Realistic about Reasons (BRR) is a beautiful book – sleek, sophisticated, and programmatic. One of its key aims is to demystify knowledge of normative and mathematical truths. In this article, I develop an epistemological problem that Scanlon fails to explicitly address. I argue that his “metaphysical pluralism” can be understood as a response to that problem. However, it resolves the problem only if it undercuts the objectivity of normative and mathematical inquiry.

I examine a distinctive kind of injustice which arises when people are maltreated in their capacity as potential conveyors of knowledge. Extant discussions of testimonial injustice usually assume that the injustice occurs when an audience ignores the claims made by a testifier. This assumption obscures the fact that there are occasions where the best framework for thinking about testimonial injustice is that of inappropriately rejecting, not ignoring, those claims; the injustice differs in these two kinds of case. Light is thrown (...) on the injustice involved in inappropriate rejection by examining the epistemic import of the distinctive second-person interrelations in play in such testimonial interactions.

Ernst Cassirer’s book Substanzbegriff und Funktionsbegriff is a difficult book for contemporary readers to understand. Its topic, the theory of concept formation, engages with debates and authors that are largely unknown today. And its “historical” style violates the philosophical standards of clarity first propounded by early analytic philosophers. Cassirer, for instance, never says explicitly what he means by “substance-concept” and “function-concept.” In this article, I answer three questions: Why did Cassirer choose to focus on the topic of concept formation? What (...) did Cassirer mean in contrasting “substance-concepts” and “function-concepts”? How does Cassirer’s polemic against traditional theories of concept formation lead to the distinctive philosophy of mathematics that he defends in the book? I argue that Cassirer’s contrast between substance-concepts and function-concepts includes a series of interrelated contrasts—contrasts that touch on issues in logic, metaphysics, epistemology, and the theory of objectivity. Cassirer’s defense of mathematical structuralism flows out of a progressively unfolding and intricate argument that begins with epistemological problems in the theory of concept formation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.3 (2003) 112-118 [Access article in PDF] Hong Kong Art: Culture and Decolonization, by David Clarke. Durham, North Carolina: Duke University Press, 2002, 240 pp. Paper. The issue of identity is a "vicious" circle in relation to Hong Kong's return to China in 1997. The more one talks about it, the more it is to be talked about as if it is a (...) phenomenon at a very special moment. But isn't not talking about Hong Kong identity in a certain period of time also a "vicious" circle, in which the lack of noise invites further silence?David Clarke's Hong Kong Art is, in a sense, an initiation of Hong Kong art as a "vicious" circle. In this sense, a concrete affinity between a text and its subject matter is significantly established. This is one of the ideals, potentials, and powers of all books written for the sake of being read and having actual effect. In this respect, this "vicious" circle is not vicious in a negative sense. It is through such interactivities that a book establishes a positive link with its subject matter.Hong Kong Art investigates "a particular historical moment in which HongKong art came into its own" (p. 10) and dwells upon the "local-ness of recent Hong Kong art" (p. 8). Nevertheless, Clarke deliberately avoids introducing a chronological survey of "Hong Kong art history as a whole" (p. 10). His solid research draws on the colloquial meanings of Hong Kong art in connection with the dynamics among different languages (Cantonese, Mandarin, and English), local receptions of art as reflected in local media, as well as backgrounds of artists, artworks, and political and cultural developments, among others. All this is necessary for a book that examines theemergence of Hong Kong identity. This is the case especiallyas "[n]o adequate survey exists of Hong Kong art as a whole," albeit surveying Hong Kong art as a whole is not the book's objective. Clarke's meta-survey about surveys on Hong Kong art is given in an endnote, which I also quote here in a note for the reader's reference. "The present author's Art and Place: Essays on Art from a Hong KongPerspective (Hong Kong, 1996) attempts to give a picture of the Hong Kong art world in the period immediately prior to the one covered by this text, and includes [End Page 112] some discussion of art from earlier periods as well. Petra Hinterthür'sModern Art in Hong Kong (Hong Kong, 1985) attempts a brief survey, but is of course unable to throw light on more recent developments. A chronology of Hong Kong art development from 1922 to 1994 is given in Hong Kong Artists. Volume 1 (Hong Kong, 1995), pp. 21-32. A rather patchy and sometimes imprecise chronology of Hong Kong artistic events from 1967 to 1998 isgiven in Gao Minglu, ed., Inside Out: New Chinese Art (Berkeley, 1998), pp. 207-11. The latter chronology also covers political and other broader historical events of the period. A valuable resource (in Chinese) for research on the early period of Hong Kong art is provided by Edwin Lai and Jack Lee, 'A Chronology of Visual Arts Activities in Hong Kong, 1900-1930,' in Besides: A Journal of Art History and Criticism 1 (1997): 135-230" (p. 211).With regard to the book's "ideal" link with its subject matter, I will now discuss the book's actualization of what it sets out to examine. The inadequacy of surveys on Hong Kong art (whether or not as a whole) manifests the relative tranquility in acknowledging that Hong Kong art is distinct. In view of this, the book itself is an intervention that (further) actualizes what it talks about. This is the case particularly in light of its predecessors' "vicious" circle of "silence," let alone those simplifications reducing Hong Kong art to either a Westernized product or a Chinese branch.The "Introduction" of Hong Kong Art begins with a critique of Western art history practices such as Gardner's...

Many contemporary proponents of hylomorphism endorse a version of hylomorphism according to which the form of a material object is a certain kind of complex relation or structure. Structural approaches to form, however, seem not to capture form’s traditional role as the guarantor of diachronic identity, since more “dynamically complex” material objects, such as living organisms, seem to undergo, and survive, various structural changes over the course of their existence. As a result, some contemporary hylomorphists have looked to alternative, non-structural (...) approaches to form. One of the leading non-structural approaches is the powers approach, according to which the form of a material object is a certain kind of power continuously activated in the object or in its material parts. In this paper, I begin by offering an overview and assessment of this powers approach to form. I argue that while the powers approach captures some crucial elements for understanding the nature of more dynamically complex material objects, when we press on the details of the view we find that it actually points to a related, but importantly distinct, third approach to understanding form, according to which the form of a material object is a certain kind of activity or process in which the material object or its parts are continuously engaged. I call this third approach “Hyloenergeism”. In the second half of the paper, I consider what such a view of material objects might look like and what its principal virtues might be. (shrink)

Predicates of personal taste have attracted a great deal of attention from philosophers of language and linguists. In the intricate debates over PPT, arguably the most central consideration has been which analysis of PPT can best account for the possibility of faultless disagreement about matters of personal taste. I argue that two models of such disagreement—the relativist and absolutist models—are empirically inadequate. In their stead, I develop a model of faultless taste disagreement which represents it as involving a novel incompatibility (...) relation between preferences that I call type-noncotenability. This model is available to all parties in the ongoing debates about PPT, but it points up an advantage enjoyed by expressivist accounts of PPT. In closing, I consider four objections against the model that, while failing to fully undermine it, open up promising avenues of inquiry about the nature of disagreement. (shrink)

John Dupr argues that 'scientific imperialism' can result in 'misguided' science being considered acceptable. 'Misguided' is an explicitly normative term and the use of the pejorative 'imperialistic' is implicitly normative. However, Dupr has not justified the normative dimension of his critique. We identify two ways in which it might be justified. It might be justified if colonisation prevents a discipline from progressing in ways that it might otherwise progress. It might also be justified if colonisation prevents the expression of important (...) values in the colonised discipline. This second concern seems most pressing in the human sciences. (shrink)

I am grateful to Sean Carroll, Paul Horwich, and Sarah McGrath for their stimulating responses to Morality and Mathematics (M&M). Their arguments concern the reality of unapplied mathematics, the practical import of moral facts, and the deliberative and explanatory roles of evaluative theories. In what follows, I address their responses, as well as some broader issues.

In _Nonsense upon Stilts¸_ first published in 1987, Waldron includes and discusses extracts from three classic critiques of the idea of natural rights embodied in the 1789 Declaration of the Rights of Man and the Citizen. Each text is prefaced by an historical introduction and an analysis of its main themes. The collection as a whole in introduced with an essay tracing the philosophical background to the three critiques as well as the eighteenth-century idea of natural rights which they attacked. (...) But the point of reproducing these works is not merely historical. Modern attacks on ‘rights-based’ political philosophy mirror the concerns of Bentham, Burke and Marx. Jeremy Waldron has therefore added an extensive concluding essay which relates these classic texts to the modern discussion of rights and re-examines the idea of rights in the light of contemporary critiques. This text provides an invaluable teaching tool for courses in politics and philosophy. (shrink)

But that which remains the poets have founded.In contemporary rhetorical theory, the relationship between rhetoric and art tends to be articulated in terms of aesthetics. This increasingly popular discourse on “aesthetic rhetoric,” however, is characterized by a remarkable diversity. The rhetoric of fiction, poetry, and other literary genres, for example, has been explored in these terms (e.g., Booth 1983), as has the rhetoric of film (Haskins 2003), photography (Hariman and Lucaites 2007), and even natural landscapes (Clark 2004). From a different (...) perspective, aesthetics has been distilled to a range of “features” or “elements” that a given text is said to possess. Nathan Crick and Jeremy Engels, for example .. (shrink)

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

Issues pertaining to sex and gender continue to be some of the most hotly debated topics of our time. While many of the most heated disputes occur at the level of politics and public policy, metaphysics, too, has a crucial role to play in these debates. In this essay, I explore several key metaphysical debates concerning sex and gender through the lenses of two important areas in contemporary metaphysics: the metaphysics of essence and the ontology of the human person. The (...) goal here is not to advocate any particular position on these issues, but to show how the tools of contemporary metaphysics can help to offer a more comprehensive map of the conceptual terrain, indicating where major areas of agreement can be found and where the most important disagreements really lie.

The dominance in normal awareness of visual percepts, which are linked to space, obscures the fact that most thoughts are non-spatial. It is argued that the mind is intrinsically non-spatial, though in perception can become compresent with spatial things derived from outside the mind. The assumption that the brain is entirely spatial is also challenged, on the grounds that there is a perfectly good place for the non-spatial in physics. A quantum logic approach to physics, which takes non-locality as its (...) starting point, offers a non-reductive way of reconciling the experience of mind with the world description of physics. For further progress it is necessary to place mind first as the key aspect of the universe. (shrink)

This book analyses the concept of scientific explanation developed by French disciples of Descartes in the period 1660-1700. Clarke examines the views of authors such as Malebranche and Rohault, as well as those of less well-known authors such as Cordemoy, Gadroys, Poisson and R'egis. These Cartesian natural philosophers developed an understanding of scientific explanation as necessarily hypothetical, and, while they contributed little to new scientific discoveries, they made a lasting contribution to our concept of explanation--generations of scientists in subsequent (...) centuries followed their lead.
